Detailed Description

Unified mesh helpers: read, prepare, build boundary, serialize.

Thin wrappers that compose the canonical mesh assembly pipeline from lower-level UnstructuredMesh / UnstructuredMeshSerialRW methods. Mirror the Python helpers in DNDSR.Geom.utils.

See docs/dev/mesh_helpers_design.md for the design document.
